Question
7.3 An electrolysis cell containing CO2 and 0.100 kg of water is run at 1.00 amp for 10 hours. Sixty percent (60%) of the electrons passed go to making oxalate. What is the molality of oxalate at the end of this experiment? 7.4 ( and obtained a final aqueous solution that only contained the sodium salt of oxalate. The solution is found to freeze at 264.63 K. What is the molality of oxalate in this solution? (K = 1.86, Kb= 0.513 for water) Suppose one carried out an experiment similar to the experiment in 7.3

In class, we talked about several products that one might electrochemically convert CO2 into as a way to reduce the amount of climate-impacting CO2 in our atmosphere. One very interesting product that we did not discuss in class is the dianion, oxalate, a substance formed from two CO2 molecules. Oxalate dianion 7.1 Write out a balanced half reaction for the formation of oxalate [C2O4]2- from CO2 in water. 7.2 How many coulombs of electrons are required to reduce 2 moles of CO2 to oxalate?
